When the rocking chair is unfolded, the second bending section 6 isslightly inclined toward the rear side, and the first end portion of thethird supporting bar 10 is at a certain distance from the fifthconnecting member 11. Consequently, a cushioned cloth (not shown in thefigures) is hung on the first end portion of the second bending section6 and the first end portion of the third supporting bar 10 to form acushion and a backrest. As shown in FIGS. 2-3, when folding the rockingchair, two hands of a user can grasp the first end portion of the thirdsupporting bar and the first end portion of the second bending section6, respectively. Then, the chair can be folded, with the person foldingthe chair using some amount of force. When the first connecting member 3slides to a position close to the third connecting member 7, it isdifficult for the user to further fold the rocking chair. At this time,the rocking chair is not compact enough. Since the third connectingmember 7 is pivotally connected to the rocking bar 1, the firstconnecting member 3 is allowed to further approach the third connectingmember 7 by lifting the second end portion of the rocking bar 1 in sucha way that the rocking chair becomes very compact in a folded state.

In some other embodiments, the twenty-sixthpivot shaft and the twenty-seventh pivot shaft are independent pivotshafts that are different from the first pivot shafts.

As shown in FIG. 6, embodiment 3 is different from embodiment 1 in thatthe armrest is not connected to the second supporting bar 8. Therefore,the second end portion of the second supporting bar 8 is not higher thanthe fifth pivot shaft, and the first end portion of the first frontcrossbar extends to form the first handle 20 for setting the armrest,and the first end of the second front crossbar extends to form thesecond handle 21 for setting another armrest. The armrests in thisembodiment are made of a flexible material such as cloth or plastic.Moreover, one end of one of the armrests is fixed on the first handle 20and the other end is fixed on the second bending section 6. One end ofthe other of the armrest is fixed to the second handle 21, and the otherend is fixed to another second bending section.
